Aware eaters of water: An idea for water labelling

Food represents 90 % of the water consumption of an individual and the agricultural sector uses on average 70 % of the freshwater withdrawn from surface and aquifers for irrigation purposes globally. From the perspective of a sustainable growth, oriented towards optimizing the use of green water and reducing that of blue water, i.e. irrigation waste and inefficiencies, it is essential to raise citizens’ awareness and promote more sustainable consumption. For this purpose, this contribution will discuss the possibility of guiding the commercial choices we, the citizens, make by means of a method for labelling water sustainability. This hypothesis of labelling provides “qualitative” information on the typology and origin of the water used to produce any type of food we consume.
